Postcss only one :root

A PostCSS plugin to remove all instances of “:root” conditionally from a stylesheet.

This plugin is very basic. It removes all instances of :root except for the stylesheets that have "postcss-allow-root" inside the file. I built this as I used automatical localised imports for my Webpack scss files, which occured in duplicate references to the :root selector variables.

Installation

npm install --save postcss-conditional-root

Example

variables.scss

:root {
    --color-blue: blue;
}

file.a.scss

@import "./variables";
.something-1 {
    color: var(--color-blue);
}

file.b.scss

@import "./variables";
.something-2 {
    color: var(--color-blue);
}

styles.scss

The following input file will be the only output to recieve the root variable.

    /* postcss-allow-root */
    @import "./file.a.scss";
    @import "./file.b.scss";

Output

:root {
    color-blue: blue
}
.something-1 {
    color: blue;
    color: var(--color-blue);
}
.something-2 {
    color:blue;
    color: var(--color-blue);
}

Usage

See the PostCSS documentation for examples on how to use this plugin in different environments. This plugin takes no options.
